During transportation, personal area network (PAN) host devices may often interface with PAN client devices via potentially complex PAN protocols. In the instance of a disconnection, the system may attempt to determine whether the user has intended to disable the connection, or whether the PAN host device experiences a non-intentional disruption of service (sometimes referred to as an “interference drop”) due to, for example, interference jammers or other devices that produce signals that interfere with the PAN session. In these instances, the PAN host device should try to recover the connection only if it is an interference drop so as to respect user intention. In both cases, the PAN host device may detect a ping timeout and attempt to recover the projection state by sending a start request over the PAN. On an intentional disconnect, the PAN client device may respond with a phone network disabled message status, indicating to the PAN host device that the user has intended to disable the connection. On a non-intentional disconnect (e.g., an interference drop), the PAN host device may attempt to reconnect to the PAN client device. Due to interference, it would fail to connect. The PAN host device may then determine that it is likely in a network interference zone, due to the PAN client device not responding that it is able to connect to the PAN host device. The PAN host device would then be able to retry multiple times to recover the connection. In this way, the PAN host device adheres to the user’s request to stay disconnected from the PAN host device if the disconnection was an intentional disconnection or recovers when the disconnection was a non-intentional disconnection (e.g., due to an interference signals).
